Foundation & Basement Waterproofing
Keep moisture out and protect your home from mold, mildew, and structural decay.
Moisture intrusion quietly damages homes — feeding mold, rotting wood, and weakening the foundation. Grand Lake Foundation Repair Plus provides interior and exterior waterproofing throughout Grand Lake and Northeast Oklahoma to seal out water and keep your basement, crawl space, and foundation dry.
We apply waterproof membranes, install interior drainage and sump systems, and seal vulnerable areas where water finds its way in. The result is a healthier home, cleaner air, and a foundation protected from costly water damage.

Frequently Asked Questions
What's the difference between drainage and waterproofing?
Drainage moves water away from your home; waterproofing seals the foundation so any remaining water can't get in. The two work best together.
Do I need interior or exterior waterproofing?
It depends on the water source and your foundation type. We inspect first and recommend the most effective, cost-efficient approach for your home.
Can waterproofing get rid of basement humidity?
Yes. Combined with proper drainage and sometimes a sump pump, waterproofing dramatically reduces humidity, mold risk, and musty odors.
